Crystallography of Stercorite

Crystal System:
Triclinic
Cell Parameters:
a = 6.92 Å, b = 10.61 Å, c = 6.43 Å
α = 98.29°, β = 90.42°, γ = 71.16°
Ratio:
a:b:c = 0.652 : 1 : 0.606
Unit Cell Volume:
V 441.75 ų (Calculated from Unit Cell)
Morphology:
Crystals short prismatic (artificial); Pseudo-monoclinc. Crystalline masses and nodules (natural).
Twinning:
Repeated twinning of triclinic individuals on {010} simulates monoclinic symmetry. Reentrant angles are usually lacking.
